# bio (long form, separated for readability)
bio: |
  Mīrzā Muhammad Tarāghāy bin Shāhrukh, born 22 March 1394, inherited Samarkand from his father Shah Rukh and presided over the cultural peak of the Timurid Renaissance. Between 1417 and 1429 he built madrasahs in Samarkand and Bukhara and raised the great Ulugh Beg Observatory, the largest in Central Asia — scholars later called him the most important observational astronomer of his century. He spoke five languages and pushed forward trigonometry and spherical geometry in service of the sky. But his scientific brilliance never translated to governance: he failed to consolidate power, and family and rivals circled. On 27 October 1449, fifty-five years old, he was overthrown and assassinated.
